Recently, corporate social responsibility (CSR) has been received extensive attentions in emerging markets. In this paper, we explore the impact of competition on CSR in supply chains, where the buyers strategically make CSR efforts with their common supplier to capture consumers with CSR awareness. We derive conditions for each firm’s optimal CSR efforts, strategy preferences and CSR implications in monopoly and duopoly scenarios. Compared with the monopoly scenario, the supply chain is more likely to be irresponsible and reduce the total CSR effort level in the duopoly scenario. However, the effect of competition is weakened when the competitive intensity increases.

最近，企业社会责任（CSR）在新兴市场受到了广泛关注。在本文中，我们探讨了竞争对供应链中企业社会责任的影响，在此采购商从战略上与他们的共同供应商共同努力以吸引具有企业社会责任意识的消费者。我们得出了在垄断和双头垄断情况下每个公司的最佳CSR努力，战略偏好和CSR含义的条件。与垄断情景相比，供应链更有可能不负责任，并降低了双寡头情景中企业社会责任的总体水平。但是，当竞争强度增加时，竞争的作用就会减弱。
